Cable Test and Diagnostics
Cable testing and diagnostics provides information about the cable’s global condition (e.g. the cable’s overall insulation system), and will reveal localised problems, such as poor joints and terminations; it will also reveal localised weak spots in the insulation. Various cable tests are carried out to spot potential failures before they can cause severe outages. Megger cable test equipment provides access to all of the technology needed to make informed cable management decisions through the different stages of the cable’s life cycle.

Partial Discharge
Is a localized dielectric breakdown (DB) (which does not completely bridge the space between the two conductors) of a small portion of a solid or fluid electrical insulation (EI) system under high voltage (HV) stress.

DC Insulation Testing
Diagnostic insulation testing today represents over a hundred years of constant development. When Sydney Evershed pioneered the first insulation tests in the late 19th century, the only measurable values were insulation at 500 volts and a basic continuity check. However, measurement techniques have continuously evolved to keep pace with new insulation technologies. From electronic design and household wiring to generators and power transmission systems, all different kinds of insulation must operate at a safe minimum value.

UHF PD Detector
Handheld online PD substation surveying system. The UHF PD Detector is the ideal tool for quick, non-invasive surveys in MV and HV substations and should be part of the toolkit for all maintenance and service teams. Due to its high measurement bandwidth, the UHF method provides accurate local online partial discharge (PD) measurements on HV components such as cable end-terminations, surge arrestors, voltage transformers and isolators.

AC Insulation Testing
AC insulation tests are a popular response to the increasingly demanding industrial, power and domestic marketplaces. Insulation materials have had to become more efficient to keep up with demand; more efficient equipment requires less insulation material to meet the minimum acceptable value of insulation resistance. In turn, cables have become smaller and lighter. However, under certain higher stress testing conditions such as DC testing, cables like Crossed Linked Polyethylene (XLPE) can quickly degrade.

Insulation and Continuity Tester
MIT2500
The MIT2500 insulation and continuity tester has been designed for motor and cable testing, specialist applications and electrical testing applications, where operation voltages exceed 1000 V and higher insulation test voltages are needed. The MIT2500 offers both fixed range voltages of 50 V, 100V, 250 V, 500 V, 1000 V and 2500 V, as well as a variable range that allows any voltage between 50 V and 2500 V to be "dialled in". This is supported by the new test voltage feedback control, which maintains the output test voltage to within 2% of the selected range, even when under test.

Dynamic Electric Motor Analyzers
Baker's dynamic motor test and monitoring instruments are built to conduct condition monitoring tests of motors and generators from a Motor Control Centre (MCC), or through a Baker EP1000 connection unit. The Baker EXP4000 dynamic motor analyser is a low-voltage, AC- and battery-operated instrument that test motors and generators while they are in operation. The EXP4000 provides health and performance data on the motor, the motor's load, and incoming power to assess motor performance and suitability in context of the entire machine system it supports.

Transformer Insulation Testing
The primary test methods used to assess the condition of the active insulation components in transformers and bushings, on site, include:1) power factor/tan δ,2) variable frequency power factor/tan δ (1 - 500 Hz)3) dielectric frequency response (DFR) [a dielectric response method], and4) moisture in oil measurements (for transformers).

Loop Testing
Megger loop testers offer both traditional measuring techniques and state of the art “non-RCD Tripping” technology. Use these products to determine the prospective earth fault current, which is the maximum current able to flow in a phase-earth fault in an installation, and also to indicate the prospective short circuit current which is the maximum current able to flow in the event of a phase-neutral fault.
